Smash Pictures Inc., the makers of Fifty Shades of Grey: a XXX Adaptation, a porn movie version of the kinky bestseller, are being sued by Universal Studios (which acquired the rights to make a film version) and Fifty Shades Ltd. (a U.K. licensing company) for copyright infringement and false advertising, among other charges.

“Defendants [had a] knowing and willful violation of Plaintiffs’ copyrights in E L James’s bestselling novels Fifty Shades of Grey, Fifty Shades Darker, and Fifty Shades Freed (the “Fifty Shades Trilogy”) by way of the production and distribution of adult films that take wholesale the dialogue, characters, and storyline from the Fifty Shades Trilogy,” said the lawsuit filed Tuesday and obtained by EW.

A part of the lawsuit is quotes director of the XXX Adaptation gave to media last year that said the porn would be “very true to the book.” Universal argues in the lawsuit: “XXX Adaptation is not a parody, and it does not comment on, criticize, or ridicule the originals. It is a rip-off, plain and simple.” The suit also features chunks of text from both the book and the movie to show how similar they are.
